'Delivery from Project: Edit Delivery Items' screen
There are 5 lines item don’t have 'Delivery Qty'

What is the reason please. User is expecting qty for this 5 materials.
What do I check next.
Thank you

The quantity proposed is limited by availability check.
Normally, you configure delivery to not create an item with quantity zero, but if you allow an item with zero quantity and there are none available (according to availability check configuration) you will get items with zero quantity.
